Definitions

  • the invention relates to pliers for processing conductor ends according to the preamble of patent claim 1.
  • the known pliers are stripping pliers which have two handles which can be moved relative to one another, at least one processing station for stripping conductor ends and a drive device via which the processing station can be driven when the handles are actuated.
  • the invention has for its object to provide a pair of pliers with which the conductor ends can be processed in different ways, with individual processing functions of the pliers should be selectively switchable, directly through the sequence of movements during the machining process.
  • a pair of pliers according to the invention is characterized in that at least one further processing station which can be driven by the drive device is present, and in that at least one of the processing stations can be coupled to the drive device with the aid of the conductor end to be processed.
  • a combination pliers which has a plurality of processing stations which can be driven by the drive device, but not all of which are permanently driven by the movement of the handles via the drive device. At least one of the processing stations remains uncoupled from the drive device until it is actually needed. This allows the wear of this machining device to be reduced, while on the other hand the pliers can be operated with less effort when the machining station is uncoupled.
  • the coupling of the processing station to the drive device takes place directly in the course of the movement of the conductor end or using the conductor end itself, so that no further adjustment processes need to be carried out by the user. This makes handling the pliers much easier.
  • a processing station of the pliers which is permanently driven by the drive device when the handles are moved, can be, for example, a stripping station, while the processing station that can be coupled to the drive device can be a crimping station. Stripping of conductor ends and the crimping of z. B. ferrules on conductor ends are processes that generally follow one another directly. Both functions can be carried out with the pliers according to the invention, so that it is no longer necessary to use separate pliers for these machining operations. If only stripping is to be stripped, the crimp function remains practically switched off, so that the pliers can be operated with less effort.
  • the pliers can also have additional processing stations, for example a cutting station for cutting conductors.
  • this cutting station does not necessarily have to be driven by the drive device.
  • the cutting devices of the cutting station can also be attached directly to the handles.
  • the pliers 1 according to the invention have a one-piece, hollow pliers body 2, the rear part of which is formed by an upper and immovable handle 3 is formed.
  • the front part of the pliers body 2 is designed in the form of a fixed jaw 4.
  • a cover 5 of the pliers body 2 is pivotable about an axis 6, so that the inside of the pliers body 2 is accessible from the upper side of the pliers 1.
  • a movable jaw 8 is pivotally mounted in the lower region of the pliers body 2 by means of a bearing pin 7. It is opposite the fixed jaw 4.
  • a lower handle 11 of the pliers 1 is integrally connected to a drive part 12, the drive part 12 being pivotably mounted on the pliers body 2 by means of a bearing pin 13.
  • the lower handle 11 is thus pivotally held on the pliers body 2 via the drive part 12 and the bearing pin 13, so that a relative movement between the lower handle 11 and the upper handle 3 is possible.
  • a tension spring 14 engages the drive part 12 above the bearing pin 13 and, on the other hand, is connected to the pliers body 2 at a point which lies in the direction of the upper handle 3. With the help of the tension spring 14, the lower handle 11 is thus rotated clockwise around the bearing pin 13, so that the tension spring 14 tries to keep the handles 3 and 11 in a spread position.
  • a short row of teeth or a tooth gap 15 at the rear end of the drive part 12 works together with a spring-loaded locking hook 16 rotatably mounted in the pliers body 2 as a lock against premature opening of the pliers 1.
  • a crimping station 17 In the upper and front part of the pliers body 2 there is a crimping station 17, to which a crimping drum 18 and a crimping lever 19 belong.
  • the crimping lever 19 is driven with the aid of the drive part 12, while the drive part 12 also ensures the rotation of the crimping drum 18, specifically with the aid of a transport lever 20 which can be seen in FIG. 4.
  • the drive part 12, the articulated lever 10 and the transport lever 20 form a drive device 21.
  • Fig. 2 shows a cross section through the upper handle 3 along the line AA of Fig. 1.
  • the upper handle 3 is hollow and has a bottom 3a in its lower region, which laterally with the walls of the handle 3 is connected.
  • the bottom 3a also extends from the handle 3 into the pliers body 2 and is guided up to the crimping station 17.
  • contact elements can be stored which are to be crimped with wire ends, for example wire end sleeves 22, which are chained together in a band. They are fed to the crimping station 17 with the aid of a supply and transport station 23 positioned on the floor 3a near the crimping station 17.
  • the cross-sectional shape of the lower handle 11 is shown in more detail in FIG. 3. This is a cross section along the line B-B in FIG. 1.
  • the lower handle 11 is open in the direction of the upper handle 3 and is essentially U-shaped.
  • FIGS. 4 and 5 The most important components for carrying out the stripping function are described in more detail below with reference to FIGS. 4 and 5.
  • the same elements as in FIGS. 1 to 3 are provided with the same reference numerals.
  • a pair of cutting jaws 24, 25 is arranged, which are integrally connected to an elongated pulling element 26.
  • Cutting jaws 24, 25 and tension elements 26 can, for. B. be made of plastic.
  • the upper cutting jaw 24, which rests on the fixed clamping jaw 4, carries an adjustable end stop 27 for a conductor end 28 to be stripped.
  • the end stop 27 can be displaced in a clamping manner in a longitudinal slot 29.
  • the cutting jaws 24 and 25 each have knives 30 and 31 in the front area for severing the insulation of a conductor end.
  • the lower cutting jaw 25, which is flexibly or pivotably connected to the upper cutting jaw 24 in its rear region, is guided by the movable clamping jaw 8.
  • the movable jaw 8 rotates clockwise around the bearing pin 7, on the one hand the conductor end 28 is clamped between the jaws 4 and 8, while on the other hand the cutting jaws 24 and 25 are moved towards one another, so that the knives 30 and 31 isolate them of the conductor end 28 can cut.
  • the movement of the lower jaw 8 and thus also of the lower cutting jaw 25 takes place by driving the articulated lever 10, which slides along the control surface 9 of the movable jaw 8, as will be explained.
  • This articulated lever 10 also serves for the longitudinal displacement of the cutting jaws 24 and 25 in the direction of the handles 3 and 11.
  • the upper and lower cutting jaws 24 and 24 are integrally connected to the elongate pulling element 26.
  • This pulling element 26 has two horizontal transverse arms 32 and 33 on opposite sides, which are guided in mutually opposite longitudinal slots 34, which are located in the lateral region of the pliers body 2.
  • the horizontal cross arms 32 and 33 can be rectangular or have a round cross-section. In the case of a rectangular cross section, rotation of the transverse arms 32 and 33 in the longitudinal slots 34 is not possible.
  • a downward-facing extension A is integrally connected to the elongated tension element 26, the front surface of which is directed towards the cutting jaws 24 and 25 is acted upon by the articulated lever 10 in order to move the elongated tension element 26 backwards via the extension A, which will be discussed in more detail below .
  • a resilient end portion 35 which has been obtained, for example, by bending and tapering the rear part of the tension element 26.
  • This end section 35 is supported elastically on a support element S which is attached to the lower handle 11.
  • the support element S can, for. B. have the shape of a cross bar that extends between the two side walls of the lower handle 11. If the articulated lever 10 releases the projection A, the elongated tension element 26 and, together with it, the cutting jaws 24 and 25 are moved again towards the front of the pliers 1 by the elastic end part 35.
  • the component consisting of upper and lower cutting jaws 24 and 25 and elongated tension element 26 can also be referred to as an elongated tension element for the sake of simplicity.
  • the articulated lever 10 has at its upper end a bead 10a which is pivotably mounted in a bearing 36 of the drive part 12. At its lower end, the articulated lever 10 has a sliding element 10b, for example a sliding roller.
  • the articulated lever 10 is thus held in the bearing 36 and lies between the drive part 12 and the guide surface 9 of the movable clamping jaw 8.
  • the bearing 36 is in a position which is in the forward direction with respect to the bearing pin 13 the pliers 1 is moved.
  • the elongated pulling element 26 is simultaneously carried backwards, that is to say shifted in the direction of the handles 11 and 3, since the sliding element 10b of the articulated lever 10 also presses against the front surface of the projection A and moves it backwards. If the handles 3 and 11 are released, they can therefore move away from each other again due to the tensile force of the tension spring 14, on the one hand the drive part 12 is rotated clockwise around the bearing journal 13 so that the articulated lever 10 can no longer act on the control surfaces 9 and 9a while, on the other hand, the elongated tension element 26 is moved forward due to the action of the elastic end portion 35. The articulated lever 10 no longer blocks approach A. Rather, it is also moved with this approach A to the front part of the control surface 9.
  • FIG. 6 and 7 show the structure of the movable or lower handle 11 in more detail. In FIG. 6, one side thereof and in FIG. 7, its other side can be seen.
  • the drive part 12 is integrally connected to the front part of the lower handle 11, as already explained.
  • the drive part 12 has two wall regions 12a and 12b lying parallel to one another, which each form the extensions of the side walls of the lower handle 11 and can additionally also be cross-stiffened with respect to one another. Openings 37 in the front side walls of the lower handle 11 serve to receive the rod-shaped support element 36 (FIG. 4).
  • the tooth gap 15 is only present on the right wall element 12b.
  • opening 13a in the left wall element 12a for the bearing journal 13 and the bearing 36 for receiving the one end 10a of the articulated lever 10.
  • openings 38 for fastening the tension springs are in both wall elements 12a, 12b 14 provided.
  • both wall elements 12a, 12b there are angled guideways 39 in both wall elements 12a, 12b, in which a pin 40 of the crimping lever 19 is guided.
  • This crimp lever 19 extends through both guideways 39, which are arranged congruently.
  • This transport lever 20 represents the coupling between the drive part 12 and the crimping drum 18, as will be explained.
  • Fig. 7 also shows how the articulated lever 10 in Bearing 36 is mounted and the movable jaw 8 controls.
  • the articulated lever 10 consists of two parallel webs and each has outer castors 10b which slide along the control surfaces 9, 9a.
  • a counter bearing 43 for receiving a conductor to be cut can be seen in FIGS. 6 and 7.
  • This counter bearing 43 works together with a knife 44 (FIGS. 1 and 4) which is guided into the region of the counter bearing 43 or crosses it when the handles 11 and 3 are pressed together. 1 and 4, a conductor to be cut is provided with the reference symbol 45.
  • the knife 44 can, for example, be fastened to the inner side wall of the pliers body 2. It covers a slot 46 in the side wall into which the conductor, which is only partially cut, can enter.
  • the components of the pliers 1 required for crimping are described in detail below.
  • the crimping drum 18 is mounted in the front upper region of the pliers body 2.
  • the crimping drum 18 is rotatable about an axis 18a, which is fastened to opposite side walls of the pliers body 2.
  • the axis 18a runs practically perpendicular to the plane of the pliers.
  • the crimping drum 18 can also be displaced by a certain amount in the axial direction on this axis 18a, whereby it is biased forward in the axial direction with the aid of spring force, that is to say when looking at FIGS. 1 and 4 out of the plane of the paper.
  • 1 and 4 show a plan view of the front of the crimping drum 18.
  • the crimp drum 18 has a plurality of axially extending dies 47, 48, 49 on its circumference, as shown in particular in FIG. 8 is.
  • These dies 47, 48 and 49 are suitable for receiving contact elements to be crimped to the conductor ends, which can be, for example, wire end sleeves.
  • the dies 47, 48, 49 can be of different sizes in order to be able to use wire end sleeves of different sizes for conductors with cross sections of different sizes.
  • the dies 47, 48, 49 are preferably arranged on the circumference at equal angular distances.
  • FIG. 9 shows a side view of the crimping drum 18 with a view of the die 47.
  • the crimping drum 18 has projections 50 on its left or front side, which are assigned to the respective dies. These projections 50 serve to lock the crimping drum 18 when the respective die is in a loading position in which it is e.g. B. can accommodate a ferrule.
  • the crimping drum 18 can be rotated by hand, for which purpose the pliers body 2 can be provided with a corresponding recess in the peripheral region of the crimping drum 18.
  • the front projections 50 are pressed into corresponding recesses with the aid of the spring force already mentioned, so that a certain position stabilization of the crimping drum 18 is thereby obtained.
  • the crimping drum 18 can be rotated at any time to lock a die in the loading position, in which case the crimping drum 18 is not yet coupled to the drive device 21. While the crimping drum 18 is rotated by hand, the projections 50 (locking lugs) are unscrewed against the spring force from the openings in which they are received, but the projections 50 are only so small in height that there is no axial displacement of the crimping drum 18 that great a coupling with the drive device could take place.
  • the crimping drum 18 can, so to speak, be preset in order to be able to process ferrules of a certain size.
  • the crimp drum 18 has on its periphery additional recesses 51 which are at predetermined angular distances from the dies, a crimping stamp to be described being inserted into the additional recesses 51 when a die 47 to 49 is in the loading position.
  • FIG. 8 best shows that each die on the rear side of the crimping drum 18 opposite the conductor insertion side (front) is closed with a locking tab 52 projecting beyond the circumference of the crimping drum 18. If a conductor is inserted from the conductor insertion side (from the front in FIG. 8) into a die 47 to 49, its tip comes against the locking tab 52, which leads to the entire crimping drum 18 being displaced axially backwards under the appropriate pressure. Upon subsequent rotation of the crimping drum 18 (which is then coupled to the drive device), the locking tabs 52 engage behind locking walls 53 fixed to the housing, as they are e.g. B. can be seen in Fig. 13.
  • the axial displacement of the crimping drum 18 can thus be locked for a certain time.
  • the crimping drum 18 is turned back, which means that the locking tabs are released again, so that the crimping drum 18 is axially displaced again due to the spring force.
  • axially extending projections 54 are present at a predetermined angular distance from the dies 47, such as. B. Figs. 7 and 8 show. If the crimping drum 18 is moved axially backwards by inserting a conductor end into a die 47 to 49, not only do the locking tabs 52 engage behind the locking walls 53, but at the same time the projections 54 come into engagement with a vertical slot 55 at the other end of the transport lever 20 This is best seen in Fig. 7. Now that the crimp drum 18 is in its rear Axial position is locked, due to the action of elements 52 and 53, the crimping drum 18 can now be rotated by means of the drive member 12 via the transport lever 20.
  • Fig. 12 shows the detailed structure of the transport lever 20. It consists of a key-shaped plate which has the vertical slot 55 at its front end and an angled guide slot 42 at its rear end, the opening angle of which is directed to the vertical slot 55.
  • the transport lever 20 can be guided between the rear wall of the pliers body 2 and the rear side of the wall element 12b.
  • the crimping lever 19 carries a crimping die 56 which is suitably brought up to an element to be crimped when it has been brought into the crimping position by the crimping drum 18.
  • the crimping lever 19 has a bearing device 57 at its lower end, via which it is pivotably mounted in the pliers body 2.
  • the bearing device 57 can be, for example, a reinforced hollow cylinder through which an axis A runs through (FIG. 4), which is attached to the pliers body 2.
  • the crimping lever 19 can then be pivoted about this axis A.
  • the crimping lever 19 is provided with the already mentioned pin 40, which runs parallel to the axis of the bearing device 57. With this pin 40, the crimping lever 19 engages in the angled guideway 39 which is located within the drive part 12, more precisely within both wall regions 12a and 12b. In this way, a particularly stable connection between drive part 12 and crimping lever 19 is achieved.
  • FIG. 13 shows a perspective view of the crimping drum 18 with connected supply and transport device 23 for wire end ferrules.
  • the crimping drum 18 is here in the loading position.
  • the storage and transport device 23 has a transport plate 58 which can be moved towards the crimping drum and away from the crimping drum.
  • a transport plate 58 On the lower side of the transport plate 58 protruding tabs or plastic tabs or brushes 59 are provided in the direction of the crimping drum 18, which move the wire end sleeves, here provided with the reference symbol 60, in the direction of the crimping drum 18 when the transport plate 58 approaches the crimping drum 18 is moved.
  • the transport plate 58 is biased towards the crimping drum 18 by means of a spring, not shown. This spring can e.g. B. between the transport plate 58 and the side wall of the pliers body 2.
  • the crimping drum 18 If the crimping drum 18 is axially displaced with the aid of a conductor end such that the locking tab 52 arrives behind the locking wall 53, and the crimping drum 18 is then rotated from the loading position into the crimping position, it takes on of the protrusions 54 lying above the transport plate 58, in other words presses it away from the crimping drum 18, specifically via a run-up slope 61 for the protrusion 54. This run-up slope 61 can also be clearly seen in FIG. 7.
  • the transport plate 58b has an elastic spring element 58c on its underside, which, for. B. is made of spring steel or plastic.
  • the elastic spring element 58c has a horizontal arm 58d which comes to rest on the ferrule belt and presses the ferrules 60 against their base 3a.
  • An arm 58e of the spring element 58c which runs obliquely from the top to the front or in the direction of the crimping drum 18, engages in the area between the wire end sleeve 60 closest to the crimping drum 18 and the following wire end sleeve, around the first-mentioned wire end sleeve into the die in the loading position to push when the spring element 58c is moved with the transport plate 58b towards the crimping drum 18.
  • the horizontal arm 58d slides over the ferrules without taking them along.
  • the arm 58e and the horizontal arm 58d can also be used as separate ones Elements exist.
  • the wire end sleeves themselves are shown enlarged in FIG. 14. They are chained together like a belt and lie parallel next to each other. A connecting web between adjacent wire end sleeves 60 bears the reference number 62. This connecting web 62 is cut by a knife 63, which can be clearly seen for example in FIG. 8. As soon as the crimping drum 18 is rotated from the loading position into the crimping position, the wire end sleeve 60 located in the die 47 is moved downward, so that the connecting web 62 is pulled over the knife 63 and cut by it.
  • FIG. 15 shows the pliers when the handles are fully spread (FIG. 15a), when the handles are half compressed (FIG. 15b) and when the handles are fully compressed (FIG. 15c). 1 and 15a, the crimping drum 18 is in the loading position, while in FIGS. 4 and 15b and 15c it is in the crimping position.
  • the crimping drum 18 is thereby displaced axially to the rear, against a spring force.
  • the locking tab 52 comes into an axial position that lies behind the axial position of the locking wall 53.
  • the projection 54 which is assigned to the die 47 in the loading position, comes into engagement with the vertical slot 55 of the transport lever 20. If the handles 3 and 11 are now moved towards one another, the locking tab 52 arrives behind the locking wall 53 and thus locks it Axial position of the crimping drum 18. At the same time, the die 47 moves from the loading position towards the crimping position.
  • the drive part 12 is rotated about the bearing pin 13, in the figures counterclockwise.
  • the transport lever 20 is displaced in the direction of the crimping drum 18, since the pin 41 lies in the upper region of the angularly shaped guide 42, deviating from the position shown in FIG. 4.
  • This means that the crimp drum 18 is first rotated by the movement of the transport lever 20.
  • the die 47 moves from the loading position to the crimping position (FIG. 15b) before the crimping lever 19 rotates.
  • the pin 40 moves within the angular guide 39 only in the horizontally lying branch, so that crimping lever 19 is not carried along when the drive part 12 is moved.
  • the pin 41 (see FIG. 4) runs in the lower branch of the guide 42, from the center downwards, so that the transport lever is not moved any further. If the crimping die 56 is pressed against the wire end sleeve, the crimping drum 18 remains at rest.
  • the spring 14 tries to spread the handles 3 and 11.
  • the spring 14 thus pulls the drive part 12 clockwise around the bearing pin 13.
  • the pin 41 runs in the lower branch of the guide 42 to its central region without the transport lever 20 being moved back thereby.
  • the crimping drum 18 therefore initially remains at rest.
  • the pin 40 runs downward in the vertical branch of the guide 39, so that the crimping lever 19 is rotated clockwise about the bearing axis 58.
  • the crimping die 46 is therefore removed from the crimping drum 18. If the pin 41 is located in the middle area of the guide 42 and the pin 40 in the lower area of the vertical branch of the guide 39, the next movement phase begins.
  • the pin 41 now runs into the upper region of the guide 42 and thereby pulls the transport lever 20 back towards the handles 3 and 11.
  • the pin 54 is thus taken along via the vertical slot 55, which results in a rotation of the crimping drum 18 counterclockwise.
  • the die 47 is thus returned to the loading position.
  • the crimping lever 19 remains practically at rest, since the pin 40 now only runs in the horizontal branch of the guide 39.
  • the locking tab 52 is released from the locking wall 53, so that the crimping drum 18 is pressed forward again, because of the between you and the rear wall of the pliers body 2 arranged spring.
  • the projection 54 is also removed from the vertical slot 55 so that there is no longer any coupling between the transport lever 20 and the crimping drum 18.
  • the run-up slope becomes due to the return movement of the crimping drum 18, that is to say through the axial backward displacement 61 released, since the projection 54 lying on it is also withdrawn.
  • the transport plate 58 can thus insert a further wire end sleeve into the die located in the loading position.
  • a tension spring between pliers body 2 and transport plate 58 bears, for example, reference number 58a in FIG. 4.
  • the crimping drum 18 is returned to the axial starting position in each case and counterclockwise after each movement cycle, that is to say is decoupled from the drive device or the transport lever 20.
  • the transport lever 20 is now moved back and forth, while on the other hand the crimping lever 19 is pivoted about its pivot axis A.
  • the crimping die 56 is therefore always moved into the crimping position, even if the die should be in the loading position. In order to avoid damage to the crimping drum in this case, it has additional recesses in its surface, which have the reference symbol 51 in FIG. 8. These recesses are in the crimping position when the associated die is in the loading position.
  • the crimping die 56 can therefore also perform its full movement in the latter case. It is essential that if the crimping drum is not required, that is, if no crimping process is to be carried out, the crimping drum is not rotated, since much more force has to be applied for its rotation than for the movement of the transport lever 20 and crimping lever 19.
